The Icon looks very much like a Camera. However not a very big camera. Not a Nikkon or Cannon. It looks like a older phone type. Not a Polaroid, but from just the sketch of a phone it's not possible me to determine whether or not it's a digital or older style camera or not.

At first cameras weren't too mobile and easy to use. They were bulky; it took ages to make photos and print them, but we had to start somewhere.

George Eastman started the revolution: he developed the "Kodak" film camera and started to sale it in 1888. Kodak slogan was witty: "You press the button, we do the rest". So everybody could shoot film henceforth, as it was easy as pie!

Then Polaroid suggested another trick: to shoot and print photos instantly! All process took under one minute. What a great idea! This became extremely popular, as there was no need to visit photolabs and waste time by standing in lines.

But that's not the end of the story: then Kodak made a new breakthrough and invented the digital camera. The first DSLR camera was sold in 1991 and it took the world by storm! So, the huge drawback of film was that it was impossible to see what you had just shot. Polaroid also printed shots before you could see what was on them. Digital technology allows you to see shots immediately and quickly retake them, without any printing. Nowadays techology keeps improving, so the sky is the limit!
